33i- Marsh Hawk — Circus hudsonhis. 



Length, male 19 inches; female 22 inches. 



Male — Upper tail-coverts white, forming a dis- 

 tinct white patch; upper parts gray or ashy; tail 

 barred with blackish; upper breast light gray; 

 lower breast and belly white, spotted or barred 

 with pale reddish brown. Female — a white patch 

 over tail; upperparts blackisii; head and neck 

 streaked with reddish brown; wing-coverts marked 

 with the same; underparts buffy, streaked with 

 blackish; barred tail. 



This is the hawk that courses back and forth low 

 over the marsh or other open place, where the 

 white rump-patch, long, rather pointed wings and 

 graceful sweeping flight serve unmistakably to 

 identify the species. The female is noticably 

 larger and in general darker than the male.

(See illustration, page 75.) 



A broad white tip on the black tail; upperparts 

 dark grayish slate, blackish on head and just over 

 tail ; underparts white, washed with gray on 

 breast. 



A bird of the orchard and roadside; fond of 

 chasing larger birds, especially crows; often se- 

 lects, like other flycatchers, a perch which com- 

 mands a wide outlook; the dead upper branches of 

 orchard trees, fence posts and telegraph wires are 

 favorite resting places. The notes are loud and 

 harsh and are sometimes repeated insistently.
